FIELD OF THE INVENTION

The invention relates to a panty-like type absorbent diaper destined forrepeated use and provided for that purpose with a changeable absorbentpad. The diaper pants comprise a front part, a back part and a crotchpart with an absorbent pad, while the front and back parts are extendedto side portions with fastening means.

BACKGROUND OF THE INVENTION

The multipurpose diaper panties with an absorbent body have been known,being repeatedly used either as a commonly worn underpants or serving asa diaper. The body liquids are absorbed in the same manner as in acommon diaper case, but the panty-like pants serve further to its userin an intact condition until the time and an opportunity come to replacethe soiled panty-like diaper with a clean diaper. As the user is to havea feeling of wearing underclothes, it is important that the panty-likediaper is of a panties shape, e.i., the article with a waist and legopenings, not a pants form with fastening tabs connecting duringapplication the diaper front and back parts. As well as the outer casinglayer materials for the panty-like diaper are selected such that aboveall the adult users are spared of psychologically negative feelingsduring wearing a diaper with a plastic outer casing layer.

In case the panty-like diaper is worn by children (babies) otherproblems occur upon the basis of a fact that a fair number of childrensuffer from hip joints deformations, e.g., dysplasia, and on that reasonthey have to wear for a longer period health aids for their treatment.For that purpose greater number of diapers have been commonly usedinstead of a usual single diaper, but that brings about difficultieswith diapers displacement and their deflection from a desired positionbetween children's thighs during wear, or special therapeutic aids areapplied over common diapers. So there is known, e.g., a side splint forcorrecting hip dysplasia in a harness form with rains, which system isfastened against the child's body. In order to obtain a necessary leanout of the babies' thighs a semi-rigid longitudinal portion is used,continuous in the back part and divided in the front part into two sideportions embracing the child's thighs and secured to the harness waistregion. In another embodiment the semi-rigid portion is formed as havingan increased front and back parts with reins and a central crotch partwith side portions embracing the child's thighs and fixable in aposition turned around the thighs with small strips. Wearing thetherapeutic aids of this kind presents a very uncomfortable task for achild. As well as the replacing of soiled diapers is complicated by anecessary release and refastening of the therapeutic aid.

U.S. Pat. No. 4,393,865 discloses a diaper for small babies destined toprevent or treat abnormalities of one or both hips, for example,dysplasia or joints subluxation. The diaper contains semi-rigid paddingmeans which are parts of the diaper material and intended for the baby'sthighs orientation into a desired position with an inclination takinginto consideration pelvis and side deflection. To fix the abovementioned semi-rigid orientation means on the baby's body the diaperincludes flexible closures. The orientation semi-rigid means can bedestined, e.g., for treating the inflammations of the small of the backand sacral nerves and they arc then positioned at the back body part, orthey can be destined for inflammatory illnesses of a pubic bone and thenoriented in this region with the front side located between the baby'sthighs. The diaper can be supplemented or combined with common absorbentmeans such as triangle diapers, diaper panties or disposable diapers.For example, with the orientation means for treating the small of theback and sacral nerves inflammations the diaper can contain absorbentmeans incorporated into an absorbent padding arranged as a diaper partin the vicinity of the diaper centerline, or it can contain a separateabsorbent body with retaining means by which it can be attached to thediaper substrate, e.g., by welding or to be glued to it. In this casethe absorbent body is located above the transverse orientation member.But said diaper is apt to slippage or turning out from the positionbetween the baby's thigh when used. The diaper is made of polyurethanwhich is not especially useful as an absorbent means for absorbingdischarged body fluids and makes cleaning and drying of the diaperrather difficult. The diaper fastening means, horizontal ones, do notprevent the diaper to drop off the user's waist, so the semi-rigid orpadding means are not correctly placed.

From U.S. Pat. No. 4,961,737 a therapeutic diaper is known containingthe main longitudinal panel from an elastic material having an inner andouter layers between which an internal pocket is found. On the oppositelongwise edges of the longitudinal panel, at the panel short side, thereare flexible side arms with fastening means for corresponding fastenerson the longitudinal panel outer surface at its second shorter side, forreleasable fastening of the diaper on the user's body. In thelongitudinal panel inner pocket a combined padding and an absorbent bodyis located with dimensions providing for fastening and holding thediaper in a flexible, or a closely similar position, and for bodyliquids absorption. At the longitudinal panel lengthwise edges elasticstrips can be arranged to seal the panel around the user's legs and theslip of the diaper. The diaper when used is located in a manner that thelongitudinal panel runs back from the user's back waist region down tothe crotch and again upwards to the waist region on the opposite part ofthe body, with inner layer against the user's skin, while the flexibleside arms extend from the back waist region forward and diagonally downand here their fastening means are secured to the fasteners on the outersurface of the longitudinal panel. The absorbent pad is a combined bodymade of a common absorbent and padding material with good absorbency,easily laundered, washable and driable, and repeatedly used. Althoughsuch a diaper serves both to therapeutic and common purposes,maintaining it in an applicable clean and dry condition, however, istime consuming and it is not applicable separately to individualpurposes.

SUMMARY OF THE INVENTION

The above mentioned drawbacks are solved with the absorbent diaper pantsaccording to the invention.

The absorbent diaper panties have a front part, a back part with anelastic member in the waist hole region, and a crotch part with elastichems in the diaper pants leg holes, wherein the front part and the backpart are provided with fastening means, and on the diaper pants innersurface side a changeable absorbent pad is arranged. The diaper pantsare further provided with a therapeutic orthopaedic pad characterised inthat the orthopaedic pad is located in a rectangular housing arranged onthe diaper pants facing side, while this housing is by its front andback transverse end ends, in a takeable apart manner, secured to the endedges of the front part and of the back part and the absorbent pad isinserted inside retaining means.

According to a favourable embodiment of the invention the orthopaedicpad is made of a firm elastic material and arranged changeably in therectangular housing.

According to another favourable embodiment of the invention therectangular housing has a longitudinal dimension corresponding to thediaper panties length and a transverse dimension corresponding to itsfront part width, being closed at its front transverse end edge,adjacent to the front part end edge, while the opposite back transverseend edge, adjacent to the back part end edge, is open, and therectangular housing is on both transverse end edges provided withfastening means for its securing to the diaper pants.

According to a yet another favourable embodiment of the invention thefastening means of the rectangular housing are formed by buttons,secured on the diaper pants front and back parts end edges, while theholes for the buttons are made in the corners of the front and back endtransverse edges of the rectangular housing.

According to other favourable embodiment of the invention the absorbentdiaper retaining means are formed by two bands extending over the wholewidth of the panties front and back parts and being anchored in the sideand end edges of the front and back parts, while the inner transverseedges of the bands are free with the bands thus forming pockets forinserting the absorbent pad.

The absorbent diaper panties according to the invention maintainproperties of known diaper pants with a changeable absorbent pad. Thediaper pants holding system is very simple and provides for sufficientstrength and elasticity of the panties and exclude their spontaneousopening. Even the not absorbed body fluids discharge is prevented, aswell as soiling the user's clothing. The diaper panties can serve aspants, diaper pants or diaper pants with an orthopaedic pad forprevention and abnormalities treatment. The orthopaedic pad is of such asize and location that it sits safely on a desired place when used.

DETAILED DESCRIPTION OF THE INVENTION

The absorbent diaper pants, shown on FIG. 1, are in a prior to usecondition, with not yet formed waist nor leg openings.

The diaper pants 1 have a front part 2, intended to be placed forwardson the user's body, a back part 3, intended to be placed backwards onthe the user's body, and a crotch part 4 which connects the front part 2and the back part 3 and will be located between the user's thighs. Theback part 3 has two side peripheral parts 5, 6, running in a directionout of the width W of the back part 3. On the side peripheral parts 5,6, there are side edges 7 and 8, the front part 2 has two side edges 22and 23. The parts 2 and 3 further have transverse end edges 9 and 10.The crotch part 4 has two side edges 11. As can be seen from FIG. 2,showing the diaper panties 1 in an assembled condition, the diaper pants1 have a waist hole 12 between respective transverse end edges 9 and 10,and two leg holes 13 surrounded by side edges 11 of the crotch part 4.

The diaper pants 1 consist of two material layers, cut to a respectiveshape, seen on FIG. 1, with allowances for making side edges 7, 8, 22,23 and end edges 9, 10 with the first, lower material layer. The firstlayer 15 of the material forms the outer face side of the pants 1, whilethe other material layer 16 forms the inner face side of the pants 1.The first layer 15 and the second layer 16 are placed on each other andhemmed with a hemming strip 17.

In a crotch part 4 into each hemming strip 17 in the region of leg holes13 a portion 18 with an elastic hem 19 is sown to for better placementof the diaper pants 1 on the user's body and against the side leakage ofnot absorbed body liquids.

The transverse end edge 10 of the back part 3 is formed by folding thematerial allowance length 15 over the second layer 16 edge towardsinside and stitching through all three layers together, whereby a hollowedge is originated, wherein an elastic member 20 is arranged adjacent tothe back and hips of the user. The transverse end edge 9 of the frontpart 2 is formed by a similar folding and securing of the layer 15,however, it is solid and inelastic.

To assemble the diaper pants 1 into a shape for its use, the fasteningmeans 21 are arranged on the front part 2 and the back part 3. One halfof the fastening means 21 is arranged on the side edges 7 a 8 of sideparts 5 and 6. The side edges 7 a 8 are strengthened and reinforced forthat purpose, for safe fastening of means 21, which are in this casemetal snapping buttons for mechanical fastening. The strengthening iseffected in a similar manner like folding material allowances of thefirst layer 15 and fastening with the second layer 16, as mentioned withthe end edges 9 and 10. The same strengthened side edges 22 and 23 arecreated even on the front part 2 and within them the second half of thefastening means 21 is secured.

Further, the diaper pants contain a replaceable absorbent pad 14. Thispad 14 is of a common construction. The face side of the diaper pants 1is provided, to receive the pad 14, with bands 24 extending over thewhole width of the front part 2 and the back part 3 of the diaper pants1. The bands 24 are stitched do the transverse end edges 9 and 10 of thefront part 2 and the back part 3 and to the side edges 7, 8 and 22, 23.The inner transverse free edges of bands 24 are hemmed by an inelasticstrip 25. The bands 24 form pockets 26 for inserting the absorbent pad14.

To the face side of the diaper pants 1 a takeable apart outerrectangular housing 27 is positioned. This housing 27 is closed on itsfront transverse end edge, adjacent to the end transverse edge 9 of thefront part 2, while the opposite back transverse end edge, adjacent tothe end transverse edge 10 of the back part 3, is open. The rectangularhousing 27 is on its both transverse end edges secured to the transverseend edges 9 and 10 of the front part 2 and the back part 3 with buttons28 stitched on the end edges 9 and 10, while the holes for the buttons28 are formed in the front transverse end edge of the housing 27, in itscorners, as well as in both layers of the back transverse end edge,again in its corners. The side peripheral parts 5, 6, of the back part 3stay free, i.e., the rectangular housing 27 covers only a central partof the diaper pants 1. The length dimension of the rectangular housing27 corresponds to the diaper pants 1 length, while the transversedimension corresponds substantially to the front part 2 width. Thedimensions of the housing 27 and its thickness are, of course, such thatthey correspond to the orthopaedic aid 29 dimensions.

Within the rectangular housing 27 a changeable orthopaedic pad 29 islocated destined for prevention or actual treatment of various hipjoints deformations, e.g., hip joints dysplasia. It is made of a firmelastic material. The pad 29 dimensions are adjusted to the desiredtherapeutic position of the wearer's thighs given by the thighsorientation to the desired position with an inclination takingconsideration to the pelvis and to the side inclinations of thighs.

The diaper pants according to the invention maintain properties of knowndiaper panties with a replaceable pad. The diaper pants holding systemis very simple and provides for sufficient strength and elasticity ofthe panties and excludes their spontaneous opening. Even the notabsorbed body fluids discharge is prevented, as well as soiling theuser's clothing. Any commonly known diaper of a quality absorbentmaterial with suitable characteristics can be used as an absorbentdiaper. The diaper panties can serve as pants, diaper pants or diaperpants with an orthopaedic pad for prevention and abnormalitiestreatment. The orthopaedic pad is of such a size and location that itsits safely on a desired place when used. The pants are of amultipurpose nature.
